also the time during which I kept my bride waiting before I married her; and, through a coincidence that is eagerly taken advantage of by the dream thoughts, it is also the time during which I am now keeping one of my best patients waiting for the completion of his cure. “_What are five years?_” ask the dream thoughts. “_That is no time at all for me—that doesn’t come into consideration._ I have time enough ahead of me, and just as what you didn’t want to believe came true at last, so I shall accomplish this also.” Besides the number 51, when separated from the number of the century, is determined in still another manner and in an opposite sense; for which reason it occurs in the dream again. Fifty-one is an age at which a man seems particularly exposed to danger, at which I have seen many of my colleagues suddenly die, and among them one who had been appointed to a professorship a few days before, after he had been waiting a long time. V. Another absurd dream which plays with figures, runs as follows: _One of my acquaintances, Mr. M., has been attacked in an essay by no less a person than Goethe, with justifiable vehemence, we all think. Mr. M. has, of course, been crushed by this attack. He complains of it bitterly at a dinner party; but he says that his veneration for Goethe has not suffered from this personal experience. I try to find some explanation of the chronological relations, which seem improbable to me. Goethe died in 1832; since his attack upon M. must of course have taken place earlier, Mr. M. was at the time a very young man. It seems plausible to me that he was 18 years old. But I do not know exactly what year it is at present, and so the whole calculation lapses into obscurity. The attack, moreover, is contained in Goethe’s well-known essay entitled “Nature.”_
